Description

With the discovery of the varroa mites becoming resistant to synthetic (or man-made) chemical treatments, this fact has prompted the kiwimana team to look at alternative treatment methods to keep our Bees alive. We found this new tool for applying Oxalic-Acid crystals, and the kiwimana team are really excited to introduce you to – the “Kiwi Oxalic Acid Vaporizer” !

The “Kiwi Oxalic Acid Vaporizer” is a vaporizer-unit which heats-up. You place the Oxalic-Acid crystals in the head of the vaporiser unit and the fumes are formed from the heat-exchange.
The fumes rise and are then spread by Bee-movement around the Beehive and it leaves small particles all over the hive.
The fumes, or smoke, create a kind of ‘dust of particles' which kills the mites by what is still yet to be exactly established in research, by disabling their ability to feed on the bees and they die.

This product designed and built by a Kiwi right here in New Zealand. It's a solid little unit, which will provide years of treatments.

A great addition – to form part of an Integrated Pest Management program

2017 Update: Oxalic Acid Vaporization (OAV) research, advised to us, is that you cannot overdose with Oxalic Acid Vapours – we had a struggling hive with heavy-mite-load, sac-brood in cells, deformed wings on Bees – so Margaret took advice and totally filled the head of the vaporizer and connecting to power for 3.00 minutes maximum, whilst keeping the entrances covered for a further 10 minutes, after power-source detached. Margaret then treated every 3 days.

Margaret did this for 4 weeks…results has seen that they have recovered and are coming into Spring 2017 extremely strong. Margaret now treats the colony every two weeks and inspection board checks show no mites. Margaret is looking to split and will not treat while waiting for new queen to be raised because there will be a brood break while the new-season queen is mated, the older queen colony may have a brood-break as well – but – monitor cells and inspection boards for mite presence.

User Warning, Margaret believes this colony survived because the population was still quite high, with capped brood over three full-depth frames – if your colony falls below these levels, the colony may be too low and sick to recover

– BEST ADVICE !! … DON'T WAIT TIL ITS TOO LATE – assume there are mites, monitor and move away from some of the treatments that have been proved to cause resistence in the varroa destructor mite here in New Zealand. The oxalic acid vaporization method is very non-invasive as well which enables the colony to keep the temperature at a consistent level, especially if you use a kiwimana meshboard inconjunction with the kiwi oxalic acid vaporizor.

Recommendation : if you are treating with the OAV method – or if you sell Honey – it may be required that you test oxalic acid content of the honey destined for human consumption – remember oxalic acid is present in Honey as part of its natural make-up.

Interesting Point : “….today it takes less varroa mites in a colony for it to fail as the viruses are stronger….” Dr Mark Goodwin 19.08.2017. Bayvarol and Apistan has contributed to Varroa Mite resistence (ie: stronger mites) in New Zealand research results.

The Method

The “Kiwi Oxalic Acid Vaporizer” unit is connected to a 12 volt car or motorbike battery (not included) or a 12volt 7.0amp battery (not included).
The battery – when connected to the unit – heats up the head of the unit which has a space for the acid to be placed in, then the heat converts the acid in to smoke or fumes.

The vapour doesn't affect mites under the capped cells, so we recommend that the treatment needs to be repeated once a week over 4 weeks to cover the full gestation cycle. Thereby enabling the emerging Bees to move through the fumes ‘dust' and the nurse Bees to clean cells and transfer fumes ‘dust' into cells which will have new eggs added.

The “Kiwi Oxalic Acid Vaporizer” is available exclusively from kiwimana.

The height of the vaporizer is 10 mm, so if your entrance is smaller than this then you will need to lever-up the front of the hive box with your hive-tool – Do not force your vaporiser through a tight entrance as you may damage the units' wiring.

(See comedy section on video)

You need to seal the hive to make the vaporization more effective, so ensure you can block any meshboards or upper entrances in your Beehive (we use old pillow-cases).

Brilliant product that REALLY WORKS and free from the crap synthetic and harmful toxins that destroy the very ecosystem that supports life. There was no evidence of dead bees associated with the treatment. The dead mites were present after each treatment. The process was easy and allowed time for ‘house keeping’ during the treatments. Worth a shot for those who want their bees naturally healthy and strong.

After watching the video on how to use and then trying it for my self, this is a game changer! So happy to have discovered Kiwimana and the helpful advice that comes with their products. Oxalic acid came with the package when I purchased of the vaporizer. No need to open or disturb the hive, simple and easy to use.

Very pleased. Nicely package with good instructions. I’m a bit late to use mine as my bees have been at the mites table early. I’ll return for 5th star when I try it.

Very happy with the purchase. Only one comments, it took about 2.5 to 3 min to heat up and produce the vapour, it could be user error but I did follow the instructions supplied, nevertheless it worked a treat. Very easy to use anyway and, I could see the bees grooming themselves after the treatment.

Thank you

Have treated for the past 3 weeks. One hive had high levels of varroa – now dead! Thanks for the speedy service, prompt response to my email queries and friendly advice. Am really impressed with this new treatment – wish I had started it earlier. Thanks Garry and Margaret.

Having decided as a new beek (2nd season) that oxalic acid would be the way to go for my urban Warre and top bar hives, I ordered the Kiwimana Vaporiser. I made inquiries using the voice mail tab on the website and was surprised to get a call the following day even though it was a Sunday. The ordering process was very efficient and the vaporiser arrived within a couple of days.

Instructions were straightforward and has a complete novice I have no trouble treating the three hives. Of note the end of the vaporiser holding the crystals was slightly fatter Then the entrance to the Warre hive, But it was easy deliver the box up the few required millimetres with my high school. I was delighted with the simplicity of this product which is both compact and robust.

Note: the height of the tray was slightly greater than the entrance but easily managed by levering the box a few mm with my Kiwimana hive tool. Great result – fun to use. Recommended!

Many thanks guys!

I have used another type of vapouriser but I find this one is by far superior to any others. Keep up the good work

I installed a Kiwimana mesh board in my metro hive on my front deck, which means I have the luxury of pulling it out & checking it every day. I also invested in a magnifying glass & a mini microscope so I could really check out what was in the debris on the mesh board. Alas, I found mites!!! I immediately ordered a Kiwi oxalic acid vaporizer, battery & charger from Margaret. It was so easy to use & the bees seemed unpurturbed after the treatment & the mite carnage on the mesh board was staggering. I am confident that I am doing the right thing by my city bees. Thanks so much for this great product.
